REFRIGERATOR CUT-OFF.

:PECIFICATION forming part of Letters Patent No. 537,193, dated April 9,1895.

\ Application filed January 17. 1 895. Serial No. 535 1 81. No model.)

To all whom it may concern Be it known that I, JOSEPH GOETZ, ofBrook:lyn, New York, have invented an Improved Refrigerator, of which thefollowing is a specification.

This invention relates to that class of refrigerators in which thecommunication between the ice chamber and cold storage chamber isautomatically cut off, when the door to the storage chamber is opened,so that the cold air cannot escape.

The invention consists in the peculiar construction of mechanism 'foraccomplishing this result in a simple and effective manner.

In the accompanying drawings, Figure lis a vertical central section ofmy improved refrigerator. Fig. 2 is vertical section throughv thestorage chamber; Fig. 3, a vertical section on line 3, 3, Fig. 2; Fig.4, a longitudinal section on line 4, 4, Fig. 2, and Fig. 5, aperspectiveview of the valve operating mechanism.

The letter or, represents the ice chamber of a refrigerator, whichcommunicates with the main storage chamber 1), by means of an opening 0,of the partition: 0. This opening is controlled by a valve lid 0 whichis hinged to the partition and is normally held in its open position bygravity.

(1, is the door of the storage chamber 1), which is pivoted at'its uppercorner to a slide 01', by pivot (1 and at its lower corner to slide (1by 1 pivot 11". The slides d, (1 move in grooved railsf, f, which extendalong the top and bottom of the storage chamber 17, from the fronttoward the rear thereof, at the right hand side of such chamber. Theupper slide cl, when in its rearmost position engages the valve 0 andcloses the same against its seat 0 while it releases the valve whendrawn forward. r

In use the door d, is opened in the usual manner, and when at rightanglesto the front of the refrigerator, (Fig. 4) is pushed into thestorage chamber 1), together with the slides 61', d The slide at, willin this way close the The full supply of cold air will now flow throughthe opening 0', and through a rear passage 6, to a supplemental coldstorage chamber. c.

When the door (1, is drawn out, with its slides 01, 62 the valve 0 willbe liberated and will open by gravity, so that the cold air isagainadmitted to the storage chamber b,immediately before the doord, isclosed.

The advantage connected with my construction lies in thegreat ease withwhich the door (1, may be manipulated, andthat it need not be bodilyraised, as is the case with doors which must be swung into a horizontalposition and slid along the roof of the storage chamber to cut off thecold air supply.

What I claim is l. The combination-in a refrigerator, of an ice chamberwith a storage chamber, an intervening partition, a valve controlling anopening in said partition, a door adapted to close the storage chamber,and a slide to which the door is pivoted, said slide being adapted tomove from the front to the rear of the storage chamber and to close thevalve when in its rearmost position, so that the supply of cold air iscut off from the storage chamber when the door is opened and projectedinto said chamber, substantially as specified.

2. The combination in arefrigerator, of an ice chamber with a storagechamber, an intervening partition, a valve controlling an opening insaid partition, a door adapted to close the storage chamber, an upperand a lower slide to which the door is pivoted, rails extending from thefront to the rear of the storage chamber and engaged by the slides, allbeing so constructed that the door when opened can be pushed backwardinto the storage chamber together with the slides, and that one ofthe'slides when in its rearmost position is adapted to close the valve,so as to cut off the supply of cold air from the storage chamber,substantially as specified.

JOSEPH GOETZ.
